The lengths of the sides of a right triangle are three consecutive integers, right, and solve an equation to find the three integers

the perimeter of the polygon is: [tex]5 + 5 + 6 = 16[/tex]  So, the perimeter of the polygon with vertices at   [tex](1, 2), (4, 6),[/tex] and  [tex](7, 2)[/tex] is [tex]16[/tex]  units.

To find the perimeter of the polygon with vertices at   [tex](1, 2), (4, 6),[/tex] and  [tex](7, 2),[/tex] we need to find the length of each side of the polygon and add them up.

Using the distance formula, we can find the length of each side:

The length of the side connecting (1, 2) and (4, 6) is:

[tex]\sqrt((4-1)^2 + (6-2)^2) = \sqrt(3^2 + 4^2) = 5[/tex]

The length of the side connecting [tex](4, 6) and (7, 2) is:\sqrt((7-4)^2 + (2-6)^2) = \sqrt(3^2 + (-4)^2) = 5[/tex]

The length of the side connecting [tex](7, 2) and (1, 2) \ is:\ \sqrt((1-7)^2 + (2-2)^2) = \sqrt((-6)^2 + 0^2) = 6[/tex]

Therefore, the perimeter of the polygon is:  [tex]5 + 5 + 6 = 16[/tex] So, the perimeter of the polygon with vertices at [tex](1, 2), (4, 6),[/tex] and [tex](7, 2) \ is \ 16[/tex] units.

The vector v+w has a magnitude of 2√2 and its direction is along the positive x-axis.

What is meant by vector?

A vector is a quantity that has both magnitude and direction. It is represented as an arrow with its length representing the magnitude and its direction representing the direction of the quantity.

What is meant by the x-axis?

The x-axis is the horizontal line on a coordinate plane that is used as a reference for plotting and describing the positions of points in two-dimensional space. It is often referred to as the "horizontal axis" or the "abscissa".

According to the given information

Here the vector v has a magnitude of 2 and a direction of 45° so the components of vector v are:

v_x = 2 cos 45° = √2

v_y = 2 sin 45° = √2

Vector w has a magnitude of 2 and a direction of 45° South of East. This means that the angle between vector w and the positive x-axis is 45°, and the angle between vector w and the negative y-axis is 45°. Therefore, the components of vector w are:

w_x = 2 cos 45° = √2

w_y = -2 sin 45° = -√2

Now we can add the components of vectors v and w to find the components of the vector v+w:

(v+w)_x = v_x + w_x = √2 + √2 = 2√2

(v+w)_y = v_y + w_y = √2 - √2 = 0

Answer:

If the zeroes of a quadratic function are -1 and 6, then its factored form is:

(x + 1)(x - 6) = 0

Expanding the left side:

x^2 - 5x - 6 = 0

So the quadratic function in standard form is:

f(x) = x^2 - 5x - 6

Answer:

f(x) = x^2 - 5x - 6

Step-by-step explanation:

To create a quadratic function with zeroes -1 and 6, we can start by using the zero product property to write out the factors of the equation:

(x + 1)(x - 6) = 0

Expanding the factors, we get:

x^2 - 5x - 6 = 0

This quadratic equation is in standard form with a leading coefficient of 1. Therefore, the quadratic function with zeroes -1 and 6 is:

f(x) = x^2 - 5x - 6

This function can also be graphed on the coordinate plane as a parabola with a vertex at (2.5, -10.25) and its axis of symmetry at x = 2.5. The graph would intersect the x-axis at -1 and 6, confirming that these are the zeroes of the function.

a. The total quantity of employed women among the sample of 7 who are not married yet is the random variable X of interest in this situation. b) Probability = 0.2749.

The number of successes in a defined number of independent trials with two possible outcomes (success or failure) and a constant probability of success are described by a discrete probability distribution called a binomial distribution. The number of trials (n) and the likelihood that a trial will succeed (p) serve as the two parameters that define the binomial distribution.

a. The total quantity of employed women among the sample of 7 who are not married yet is the random variable X of interest in this situation.

b) The probability of 2 women who have never been married is:

P(X = 2) = (7 choose 2) * (0.2)² * (0.8)⁵

P(X = 2) = 21 * 0.04 * 0.32768

P(X = 2) = 0.2749

c) For 2 or fewer have never been married:

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

The number 2 is the one for which the theoretical probability matches the experimental probability.

To determine which number has a theoretical probability that matches the experimental probability, we need to calculate both the theoretical and experimental probabilities for each of the four numbers.

The theoretical probability of spinning any one of the four numbers is 1/4, or 0.25. This is because there are four equally likely outcomes, and each outcome has a probability of 1/4.

To calculate the experimental probability, we need to count the number of times each number was spun and divide by the total number of spins. Here are the results:

- Number 1 was spun 9 times out of 28 spins, so its experimental probability is 9/28, or approximately 0.321.

- Number 2 was spun 7 times out of 28 spins, so its experimental probability is 7/28, or approximately 0.250.

- Number 3 was spun 6 times out of 28 spins, so its experimental probability is 6/28, or approximately 0.214.

- Number 4 was spun 6 times out of 28 spins, so its experimental probability is 6/28, or approximately 0.214.

To find the number that has a theoretical probability that matches the experimental probability, we can compare the theoretical probability to each of the experimental probabilities. The number that has an experimental probability that is closest to the theoretical probability of 0.25 is number 2, which has an experimental probability of approximately 0.250.

Therefore, the number 2 is the one for which the theoretical probability matches the experimental probability.

Answer: 2

Step-by-step explanation:

We can simplify the given logarithmic expression using the logarithmic property that states:

log a base b - log c base b = log (a/c) base b

Using this property, we can rewrite the expression as follows:

log 16 base 2 - log 4 base 2 = log (16/4) base 2

Simplifying the numerator of the logarithm, we get:

log (16/4) base 2 = log 4 base 2

Now, we can evaluate the logarithm using the definition of logarithm, which states that:

log b base a = x if and only if a = b^x

In this case, we have:

log 4 base 2 = x if and only if 2^x = 4

We know that 2 raised to what power gives 4? It is 2, because 2^2 = 4.

Therefore, we have:

log 4 base 2 = 2

Hence, the value of the given logarithmic expression is 2.

Answer: c=60

By setting up and solving a proportion that represents the ratio of blue counters to total counters in two different scenarios, we find that an estimate for the total number of counters in the bag is 60.

We can set up a proportion to solve this problem. In this case, the counters represent the total numbers in different situations. Initially, there are 15 blue counters out of an unknown total 'x'. Meanwhile, Hussain picked 6 blue counters out of 24. As these are similar situations (picking blue counters out of a total), we can express this as a proportion as follows: 15/x = 6/24 .

To solve this proportion, simply cross multiply and solve for x: 15*24 = 6*x. Simplify this to 360 = 6x. Diving both sides by 6 gives the value of x as 60.

So an estimate for the total number of counters in the bag, or 'x', is 60.

The equation of the line that passes through the points (4, 1) and (12, -3) is y = (-1/2)x + 3.

Explain the term equation

An equation is a mathematical statement that expresses the equality of two expressions or values. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are used to represent relationships between quantities and to solve problems in various fields, including mathematics, physics, and engineering.

According to the given information

We can use the point-slope form of the equation of a line to find the equation of the line that passes through the two given points.

The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is a point on the line.

To find the slope of the line that passes through (4, 1) and (12, -3), we can use the slope formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (4, 1) and (x2, y2) = (12, -3)

m = (-3 - 1) / (12 - 4) = -4 / 8 = -1/2

Now that we have the slope of the line, we can use one of the two given points and the slope to find the equation of the line. Let's use the point (4, 1):

y - y1 = m(x - x1)

y - 1 = (-1/2)(x - 4)

Distributing the -1/2, we get:

y - 1 = (-1/2)x + 2

Adding 1 to both sides, we get:

y = (-1/2)x + 3

Therefore, the equation of the line that passes through the points (4, 1) and (12, -3) is y = (-1/2)x + 3.

There are 25  persons who actually voted, the 95% confidence interval for the population of registered voters who voted in the most recent school board election is 0.2±0.07 that is (0.13, 0.27).

In statistics, a confidence interval, means  the probability which a population parameter will fall between a set of values for a certain proportion of times. Confidence intervals measure the degree of uncertainty or certainty in a sampling method. There are various types of confidence interval such as 90%, 95%, 99% etc.

A certain randomly selected sample of 125 registered voters showed that 20% of them voted in the most recent school board election.

So in 125persons the persons who actually voted are

                (125×20)/100

              = 2500/100

              = 25

For 95% confidence interval the z value is 1.96.

If we take p as probability of success that is the persons who actually voted then 1-p denotes the probability of failure.

p= 25/125= 1/5 = 0.2          n= 125

1-p= 1-(1/5)

    = 1-0.2= 0.8

The formula for confidence interval is

p± z√{p(1-p)/n}

0.2 ±1.96√{(0.2×0.8)/125}

= 0.2 ± 1.96√(0.16/125)

= 0.2± 1.96 ×0.035777

= 0.2±0.07012

The height of the pole is approximately 10.2 yards tall.

Let's use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse (the longest side).

In this case, the pole is the vertical side of the right triangle, the ground is the horizontal side, and the rope is the hypotenuse. Let's call the height of the pole "h". Then we have:

h² + 11² = 15²

Simplifying:

h² + 121 = 225

Subtracting 121 from both sides:

h² = 104

Taking the square root of both sides:

The right circular cylindrical tank which is 5 m long and 13 m in diameter holds about 663,325 liters of liquid approximately.

The formula to find the volume of a right cylindrical tank is

V = πr²h, where 'r' is the radius and 'h' is the height.

Given that, the height is 5 m and the diameter is 13 m.

Radius = Diameter/2.

Radius = 13/2 = 6.5 m.

We know that, π = 3.14.

Now, we can substitute the values in the formula.

V = 3.14×(6.5)²×5.

V = 3.14×6.5×6.5×5

V = 663.325 cubic meters.

Now, we have to convert cubic meters into liters.

We need to multiply by 1000 as a thousand liters are in one cubic meter.
